Explanation:

Step1: Analyze first story

In the first story, losing 2 points per blue - space landing and total 10 points lost. The operation should be $- 10\div - 2$ to find number of blue - space landings. Each blue - space landing causes a loss of 2 points (-2 per landing) and total loss is 10 points (-10), so number of landings is $\frac{-10}{-2}$.

Step2: Analyze second story

In the second story, losing 5 points per blue - space landing and total 10 points lost. The operation to find number of blue - space landings is $-10\div - 5$, not $-10\div - 2$.

Answer:

The first story.
